String templates revisited

Sometimes I encounter a task - create some little template, that user can easily configure. Yeah, there are many powerful template engines, or you can use {0}, {1} placeholders, or even handwritten #Id#, #Name# placeholders. But this article describes yet another way - simple and descriptive string formatters such as in ASP.NET AJAX 4.0: {Id}, {Name}, {Login}. This placeholders reflects public properties or fields of an object.
